Although I have yet to successfully trim my pup's nails as he is deathly afraid of the device despite my hours of prepping and trying to get him used to it, I'm 100% confident that, with time, it will be a breeze. This thing is virtually silent and, from testing it on my own thumbnail, works like a charm. I have no doubt that my little guy will eventualy give in and trimming will be a piece of cake.
